Sandy, I wish I could mulch more. It just gets too expensive to have to do it every other year or so. I do use Preen and Green once a year after doing the first weeding and before most of the seeds have germinated. It would help if I could do that again in July, but I usually don't get around to it. I just weed by hand as I'm out watering and dead heading. Planting close together really helps too.
